Abstract
A hand operated tool for extracting a finger grip insert glued in a bowling ball including a shaft, a T-shaped handle grip, and a tubular extractor affixed to the shaft and having a knife dull edge free end adapted to cut the insert away from the bowling ball as the tool is turned and pushed inwardly and a beveled inner surface adjacent the free end which applies a funneling force to the insert as the extractor is rotated thereabout whereby cutting of the insert is inhibited.
Claims10
A tool for extracting a finger grip insert having a passageway therethrough for receiving a finger of a bowler and which has been glued in a finger cavity of a bowling ball which comprises a tool body with a hand grip adapted to turn said body about an axis and an insert extractor including an elongated thin tubular member having an external surface and an internal surface having opposite ends, one said end being rigidly connected to said body, another said end being a free end terminating in a substantially circular dull knife edge, said internal surface terminating short of said free end, said tubular member having an internal beveled surface extending between said internal surface and outwardly to said external surface at said tree end and forming said dull knife edge, said dull knife edge being sufficiently sharp to cut a glue bond between a finger grip insert and a finger cavity of a bowling ball, and said internal bevelled surface being adapted to forcibly funnel a finger grip insert into said tubular member during rotative cutting of a glue bond by said dull knife edge to inhibit damaging a finger grip during such cutting whereby a finger grip may be reused.
A hand tool for extracting a flexible finger grip insert having a passageway therethrough for receiving a finger of a bowler and which has been glued in a finger cavity in a bowling ball, said tool including an elongated substantially cylindrical shaft member having opposite end portions and an extractor member affixed to one said end portion, a lateral cross bar handle extending on either side of said shaft adjacent another of said end portions, said extractor member including a hollow tubular member affixed at one end thereof to said shaft one end portion and another end being a substantially circular bevelled dull knife edge, said tubular member having a cylindrical internal surface and a cylindrical external surface and a tapering internal conical surface therebetween, said conical surface intersecting said internal surface of said tubular member spaced from said dull knife edge and extending laterally outwardly thereof to form said dull knife with said external surface.
